Consumer:

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Professional:

Propranolol may inhibit the oxidative metabolism of thioxanthenes. The pharmacologic effects of the thioxanthene may be increased. The mechanism may be related to competitive inhibition of CYP450 2D6-mediated first-pass metabolism. The clinical significance of this interaction is unknown. Atenolol, carteolol, nadolol, and sotalol may be considered as alternatives because they undergo renal elimination and are not expected to interact. If this combination cannot be avoided, decreased dosage of either or both drugs may be necessary and the patient should be closely monitored for cardiovascular or nervous system adverse effects.
